modification example of embodiment 1
[0039]Next, the modification example of the embodiment 1 is described. FIG. 9 is a flow chart of writing processing of the rank information according to the modification example of the embodiment 1. As illustrated in FIG. 9, in the modification example 1 of the embodiment 1, a storage process for grasping a total number of stocks for each rank is added after the graphic symbolic code is marked on the semiconductor device 1 in the writing processing of the rank information.
[0040]Next, the writing processing of the rank information is described with reference to FIG. 9. The steps of Step S1 to Step S3 are performed in the manner similar to the case of FIG. 7, and the storage process is performed in the next Step S4. In the storage process, the calculation unit 3 records the number of stocks of the semiconductor device 1 for each rank of the electrical characteristics in a memory of the calculation unit 3, for example, thereby finishing the writing processing. The semiconductor device ...
